My results show a different physical trait from reality. Why?
Just like with complex diseases, personal traits are not solely determined by a genetic factor, which is the information we analyze at tellmeGen, but are also regulated by an environmental factor that can have a strong impact on the presence of that trait. Furthermore, with current genetic knowledge, we always speak in terms of probability. Having genetic variants associated with a trait will increase the probability of presenting that trait, but the results are not definitive.
